COMBINED HARROW, SEEDER, AND MOWER.

SIEGIFICATION forming part of Letters Patent No. 445,543, dated February 8, 1891.

Application filed April 3, 1890. Serial No. 346,446. (No model.)

To all whom it may concern:

Be it known that I, HARRISON V. CONWAY, a citizen of the United States, residing at Boone, in the county of Boone and State of Iowa, have invented a new and useful Combined I-Iarrow, Seeder, and Mower, of which the following is a specification.

This invention has relation to agricultural machines, and among the objects in view are to combine three important machines in one structure-mamely, a harrow, a seeder, and a mower; to provide means for conjointly or separately operating all or each, as desirable, and this in a simple and convenient manner, all as will hereinafter appear, and be particularly pointed out in the claims.

Referring to the drawings, Figure l is a plan of a combination agricultural machine constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a side elevation. Fig. 4 is a detail in perspective of the harrow. Fig. 5 is adetail in front elevation of the cutter-bar connecting and operating mechanism.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents an oblong frameprovided with opposite bearing-boxes 2, in which is mounted a transverse axle 3, provided outside of the frame with ground -wheels 4 of the usual construction. Mounted upon the axle 3 is a master-gear 5, fixed to the axle and adapted to revolve therewith. The ground-wheels are loose upon the axle, and between said wheels and the frame-work at each side of the latter there is mounted a fixed ratchet-wheel 6. The wheels are provided upon their inner sides with pivoted pawls 7, pressed into mesh with their respective ratchet by means of springs 8, secured to the wheels. The teeth of the ratchets are disposed to the rear, so that the pawls are in engagement with the teeth only when the machine moves forward, and therefore only turns the axle at that time, and in backing said pawls ride over theteeth of their ratchets and the axle remains inactive.

At one side of the oblong frame and underneath the same there is arranged a pair of bearing-brackets 9. Opposite each other and mounted for rotation therein is a shaft 10, having a small pinion 11 meshing with the main gear and adapted to be driven thereby. The shaft is also so arranged in the bearings as to be adapted for longitudinal movement therein, so that the pinion may be withdrawn from mesh or engagement with the large gear, which is accomplished by means of a hand-lever 12, loosely engaging the shaft and pivoted, as at 13, to a standard 14, projecting up from the frame and provided with opposite locking-notches 15, the handle of the lever being within ready grasp of a person occupying the drivers seat 16, which is supported by a rearwardly disposed spring standard 17,

secured at its upper end to the frame-work andato the bracket aforesaid, said arm depending from the frame and extending to one side thereof and pivotally connected, as at 26, between two perforated ears 27,formed,

at the inner end of a finger-bar 28 of a reaper. 8o

Mounted over the finger-bar is a cutter-bar 29, terminating at its inner end in an eye 30, which eye is connected with the lower end of the bell-crank by means of a connectingrod 31, so that a reciprocatory motion is given the cutter-bar by means of the connecting rods, the bell-crank, the crank-disk, its shaft 10, and pinion 11, which motion may be stopped by a shifting of the shaft 10 through the medium of the lever controlling the same. 0

Projecting rearwardly from the oblong frame at opposite sides is a pair of bars 32, above which there is supported a. transversely-located seed-box 33, the bottom of which is perforated and covered by a seed- 5 slide 34, having perforations adapted to be thrown more or less info registry with the perforations in the box or entirely out of such registry, as occasion may require, and

for the purpose of increasing or diminishing or entirely cutting off the feed of seed. A pair of lugs 35 depend from the box near op- IHgIOCl 21, the opposite end of which loosely 7o posite ends, which lugs straddle the rear ends of the rearwardly-projecting bars, the bars and lugs being perforated and locked in removable position by means of removable pins 36, inserted through the perforations.

37 represents a Y-shaped arm, the rear end of which terminates in a hook 38 and the forward ends of which are perforated, as at 39, and removably and pivotally connected to the rear ends of the bars 3 by means of opposite pins 88. The Y'shaped arm is also provided near its rear end with an eye 39", connected with which is a curved rod 40, the forward end of the rod connecting with a hand-lever 4E1, pivoted to the longitudinal central bar of the frame and adapted to interlock with any one of a series of notches 43, formed in a locking-segment 44;. By operating the lever 41 upon its pivot it is ap-.

' arm,- and said sections are also connected by a loose connecting-rod 48. The inner longitudinal bars of the harrow-sections are connected loosely at their front ends to draftrods 47, which rods are removabl y connected witha pair of hooks 18, depending from the opposite under sides of the main frame. A pair of brackets 49, provided with bearings, is secured to the under side of the frame 1, and in the same there is mounted for longitudinal and rotary movement a shaft 49 provided near its inner end with a small pinion 50, adapted for mesh with the main gear, and near its center provided with a crank portion 51. A lever 52 has its lower end in engagement with the shaft, and is pivoted near its upper end, which projects vertically through thg frame, to a standard 53, as at 5i, said standard being provided with a pair of locking-notches 55, into which the lever is adapted to take for the purpose of reciprocating the shaft, and thus throw the pinion into and out of mesh with the gear.

57 represents an oscillating lever pivoted, as at58, to the under side of thelongitudinal beam of the frame and depending under the frame and having its rear end extending beyond the same and terminating in a hooked portion 58, loosely engaging the eye of the front bridle of the harrow. Akeeper 59 supports the rear end of the oscillating lever,and said lever is connected by a stud 00 with the seed-slide of the seed box or hopper, so that any oscillation of the lever is imparted to the seed-slide and to the front ends of the harrowsections, whereby said harrow-sections are caused to move over a zigzag course, and thus thoroughly pulverize the soil. The motion given the lever is secured by a connectinglink 61, one end of which is connected with the lever and the opposite end of which is loosely connected with the cranked portion of the shaft 49.

62 represents the tongue or d raft-bar bolted, as at 63, to the front end of the frame and haying its rear end terminating under and bolted to the front end of the central longitudinal beam, as at 6%, which beam is supported at its front end upon a transverse bolster 65, the ends of which rest upon the sides of the oblong frame 1.

From the above description it will be apparent that the harrow and seeder may be employed in conjunction with each other and the reaping mechanism removed by the withdrawal of the coupling-pin which connects the same with the outer end of the transverse arm and disconnecting the connecting-rod which connects the cutter-bar with the lower end of the bell-crank. hen this is accomplished, the lever which'governs the shaft 10 is so manipulated as to throw the pinion 11 out of mesh with the master-gear. This lever may be also used when approaching or leaving the field.

If desired, the seed box or hopper may be removed and simply the harrow used, and said harrow by manipulation of its governing-leve'r may be made to travel in a straight line or zigzag, as desired, or, furthermore, by means of the pivoted Y-shaped arm, the curved rod, and the lever to which it is connected said harrow may be swung upward out of contact with the ground or may be wholly detached with the seed-box or without the same and the mowing mechanism alone used. \Vhether used combined or separate, the machines are complete and efficient and all may be conveniently operated by a set of levers arranged within easy grasp of the hand of the operator.

A lever (37 is pivoted, as at 68, to one of the side bars of the frame and is provided with a lock or spring-bolt 69, adapted to engage a toothed sector 70.

'71 represents a curved bar, one end of which is connected to the lever 67 and the opposite end loosely connected to an eye 72, located upon the reaper. By means of the lever 67 the finger and cutter bars may be elevated above the ground and the lever 12 operated to stop the motion of said mechanism.
